Do they (cloudflare) happen to use cpanel or similar? There is a known issue, namely automatically adding an autodiscover record that point to the hoster's own system. Simply remove that setting, or if that's not possible, use the client-side registry keys to "instruct" Outlook to bypass that lookup. Take a look for example at this thread: https://social.technet.microsoft.com/Forums/exchange/en-US/4099e289-55bf-476b-a9c4-ee1377046df7/cpanel-autodiscover-conflict-with-exchange?forum=exchangesvrgeneral

    Thanks for your reply.

     

    I have now moved the nameservers to Office 365 so as to cancel out any third party issues and the problem still exits.

     

    I have used the Microsoft Connectivity web tool and it is happy with all settings.

     

    I have gone into the Office 365 DNS settings and validated everything and Office 365 has given me all green ticks so I don't understand how this is not working.

     

    Just to re-iterate, this is happening on multiple computers.

     

    Anyone seen this before?
